Introduction: Brucellosis is one of the most important zoonotic diseases that causes miscarriage and infertility in animals and causes human fever. The use of the common SS9 strain of Brucella abortus has several side effects for livestock. Brucella P39 protein is one of the plasma peripheral space proteins that is considered as one of the important immunogenic indicators. With the production of the new protein combination of P39, more studies can be done on the ability of this protein to stimulate immune responses against Brucella. Therefore, in this research, the production and purification of this protein in Escherichia coli bacteria has been done as a new compound.
method: In this experimental study, using the polymerase chain reaction, the P39 gene was propagated by the bacterium Brucella abortus. After purifying the P39 gene, it was cloned into plasmid carriers pSK+ and pGEX4T1. Therefore, pSK+-P39 and pGEX4T1-P39 structures were prepared. To produce the recombinant protein P39, the plasmid structure pGEX4T1-P39 first entered the Escherichia coli bacterium BL21. The protein was then produced by IPTG by induction of pGEX4T1-P39 plasmid. The resulting protein was purified using the orderly purification protein glutathione S-transferase. The amount of purified protein was measured using the Brad Ford method.
Results: The nucleotide sequence of the gene propagated by the cloned PCR in the plasmid carrier  pSK+ was exactly the same as the P39 gene of Brucella abortus. Production of P39 protein was performed by induction of pGEX4T1-P39 plasmid. The purified protein content was 200 micrograms per milliliter.
Conclusion: The production of the new protein P39 compound Brucella Abortus, which is unstable in the cytoplasm of the Escherichia coli bacterium, is possible using carriers with additive proteins such as pGEX4T1 in the host of Escherichia coli strain BL21.

Introduction: Familial adenomatous polyposis (FAP) is a rare disease with hundreds to thousands adenomatous polyps in large intestine which inherits in the form of autosomal dominant, but 25% of patients have no positive family history. Rectorrhagia and rectal prolapsus are the most prevalent symptoms. Diagnosis is based on clinical findings and results of colon investigation, and prompt colectomy prevents carcinoma in patient. In this article a case report of familial adenomatous polyposis is presented. Case: The patient is a 17 years old teenager, a known case of familial adenomatous polyposis, who was refered with severe obstruction signs of gastrointestinal tract. The disease was diagnosied when he was 5 years old. In 6 years old he was treated by partital colectomy and in 11 years old by total colectomy and ileorectal anastomosis. The patient was investigated by endoscopy and small bowel transit. Because of many polyps in stomach, duodenum and jejunum polypectomy, gastrectomy and duodenotomy were done. Diffuse carcinoma in situ was reported in pathology. Conclusion: Rectal and colonic polyps are rarely obsereved below 10 years old, but rectorrhagia and rectal prolapsus suspects the diagnosis of FAP in children. In the case of dysplasia and carcinoma abdominal pain, anemia and weight loss will be presented. In children with suspecting FAP, screening of extracolonic manifestation and dysplasia should be considerd and elective surgery should be done.

Introduction: In this study the effect of extracellular trans zinc and voltage sensitive calcium channels on different aspects of learning and memory has been investigated. Materials and Methods: This is an experimental study in which the effect of a calcium channel antagonist (Verapamil) and zinc chelator (Ca-EDTA), on passive avoidance learning (shuttle box apparatus) has been examined by intraperitoneal administration of defferent doses of these drugs. Data was analyzed using one way analysis of variance. Results: Result of intraperitoneal injection of 100 milimolar Ca-EDTA indicated that it has no effect on the acquisition, consolidation, and retrieval of passive avoidance learning. Verapamil (100 and 150 micrograms) as a L-type voltage gated calcium channel antagonist, decreased acquisition and consolidation but not retrieval of passive avoidance behaviour. These effects were dose dependent. The simltaneous effect of Ca-EDTA and verapamil was also studied. Ca-EDTA (100milimolar) and verapamil (100 micrograms) have negative effects on consolidation of passive avoidance learning. Conclusion: Probably, common mechanisms are involved in acquisition and consolidation of passive avoidance learning, and zinc and calium ions play interactive roles in this aspect.

Background: Glycoconjugates molecules showed a programmed changes during the development. These components in the cell-surface and extracellular matrix plays important roles for different developmental processes. In this study lectin histochemistry technique was used for identification and localization of some glycoconjugates during the development of thymus. Methods and Materials: Balb/C mice embryos from days 10 to 15 and also day 18 fetuses fixed in formalin and provided 5m serial sections of these samples for histochemical study. Slices were incubated with three types of HRP-conjugated lectins (HRP) include: SBA specified for α, β-D-N-acetylgalactoseamin (α,β-D-GalNAc), PNA specified for β-D-Galactose -(1-3)-D-N-acetylgalactoseamin (β-D-Gal-(1-3)-D-GalNAc) , MPA specified for D-Galactose (D- Gal). Results: SBA lectin was presented with decreasing intensity in the Golgi zone (GZ) and cell surfaces of mesenchymal cells, epithelial cells and T-cells microenvironment in studying days. In first day (12&13) T-cells had high reaction with SBA in membranes and GZ. PNA lectin was revealed with several intensity in basal membranes and membranes of mesenchymal cells, epithelial and microenvironment of T-cells in studying days. MPA lectin weakly presented in the endodermal and mesenchymal cells and microenvironment of T-cells in all days. Conclusion: Results indicated that glycoconjugates molecules with terminal carbohydrate of GalNAc might have a role in the development of thymus gland and maturation of the T-cells. Glycoconjugates with terminal disaccharide of Gal/GalNAc probably have significant effect on the total developmental process of thymus gland. Further, Glycoconjugates with terminal carbohydrate of Gal probably had not a key role in the development of thymus gland and T-cells or with low quantity effect.

Background: Colorectal cancer is one of the most important and most common fatal types of cancer in the world. Identifying new agents which individually or in combination with other agents induce apoptosis in tumor cells is surely of great significance in treatment of colon cancer. The aim of the present study was to assess the effectiveness of applying lovastatin and α-tocopherol individually or in combination with each other in the induction of apoptosis in human colorectal cancer cells. Materials and Methods: In this trial, HT29 cells were exposed to various concenterations of lovastatin (5, 10, and 20 μmol) and/or alpha tocopherol (10, 20, and 25, and 30 μmol). After cell count, these cells were examined through trypan blue method and DNA fragmentation technique. Results: The findings of DNA fragmentation technique showed that each of the two drugs could induce apoptosis at all of the given concentrations. In the combination of 10 μmol concentration of lovastatin and 5 and 10 μmol concentrations of α-tocopherol, induction of apoptosis was not observed. Conclusion: Based on the extensive effects of statins, the concentration of lovastatin is seen as determining in its apoptosis function, and its combination with tocopheroles in high concentrations, by inducing apoptosis, can provide novel effective strategies for prevention of human colorectal cancer.

Background: One way of embryo preservation is cryopreservation, but this process may damage and lead to the loss of the embryos, and bring about chromosomal abnormality. This has led researchers to seek techniques for short term preservation of embryos in 0-10 ºC temperatures. The aim of this study was to determine the effect of short time exposure to 4°C temperature on the expression profiles of mono-carboxylic transporter genes 1,2 ,3, and 4(MCT1-4) in 4-cell mouse embryos. Materials and Methods: In this fundamental study, forty 4-cell mouse embryos from NMRI strain were randomly divided into two groups. The first group consisted of fresh 4-cell embryos, and the second group included 4-cell mouse embryos that were exposed to 4°C temperature for 24 hours. After RT-PCR, the samples were electro-phoresised for expressing the MTC1-4 genes. Results: The expression of MCT 1-3 was observed in the first group, but the obtained results did not indicate their expression in the second group. Conclusion: Preservation of 4-cell embryos in 4°C for 24 hours inhibits the expression of MCT 1-3 genes. Keeping embryos in 4°C temperature is not a proper way for their short time preservation.

Background: Recently, reports have been made of the effects of boric acid (BA) on cancer prevention and inhibition of cancer cell proliferation. This study was designed to investigate the effects of this compound on K562 cell line as a model of chronic myeloid leukemia (CML). Materials and Methods: In this experimental trial, K562 cell line was cultured in the presence of 0.75 to 12 mmol concentrations of boric acid for 24, 48, 72, and 96 hour intervals. Anti-proliferative and cytotoxic effects of BA were measured by trypan blue exclusion test and MTT assay, respectively. Flow-cytometery was utilized for evaluating the effects of BA on cell cycle. Wright-giemsa staining was used for determining the effects of BA, and latex phagocytic assay was used for evaluating the phagocytic potential of the differentiated cells. Results: BA induced growth inhibition of K562 cells in a dose and time dependent manner after 96 hours of treatment with 12 mmol BA, cell proliferation of K562 cells was inhibited to about 83% (p<0.001). In addition, BA induced G1 cell cycle arrest in a way that for instance, after 6 days of treatment with 9 mmol BA, 98% of cell populations were at G1 level. Wright-giemsa staining and latex phagocytic assay results confirmed that K562 cells differentiated toward monocyte-macrophage lineage. Conclusion: Noticing the anti-proliferative and differentiating effects of BA, and no evidence of its adverse effects, this compound can be used as alone or in combination with other drugs in CML differentiation therapy.

Background: Brucellosis, a zoonotic disease with worldwide spread, is a common disease in Iran and is endemic in Markazi Province. Brucella osteomyelitis, on the other hand, is a rare disease. Here we reported a case of brucella osteomyelitis of the tibia following trauma. Case: The patient was a 22 year old man referring with chronic draining tibia ulcer. He had a history of trauma of the tibia, dating back to 3 years ago, for which local prosthesis had been prescribed. Later on, the prosthesis had been removed due to infection. Staining of the tissue samples indicated the presence of gram-negative coccobacill and brucella growth in the culture of excretions. Conclusion: This case was reported because of rare presentation of brucella and the educational implications of the patient with respect to the possibility of brucella development in chronic ulcers or prosthesis. Although uncommon, brucellosis should be regarded as a potential cause of osteomyelitis in patients with a record of physical contact with animals.

Background: Due to problems caused by traditional dressings, scientists have long been in search for producing alternative cellulose. Unique characteristics of bacterial cellulose synthesized by acetobacter xylinum, due to its nanostructure cellulose, resulted in attempts to devise an ideal dressing with this cellulose. The main aim of this study is to evaluate the effect of impregnated bacterial cellulose on staphylococcus aureus culture. Materials and Methods: In this descriptive-analytical study, cellulose disks synthesized by bacterial cellulose and cellulose blank disks (without antibiotic) were placed in 3.3% ciprofloxacin hydrochloride. These disks were, then, together with ciprofloxacin standard, control cellulose, and cellulose blank disks, placed on the cultured media of staphylococcus aureus. After 24 hours, the results were obtained through the measurement of growth inhibition zone. Determining the amount of antibiotic absorbed into bacterial cellulose can be done through the comparison of the effects of cellulose disks containing different concentrations of ciprofloxacin hydrochloride and ciprofloxacin standard disks. Results: Both cellulose and blank disks created a growth inhibition zone in staphylococcus aureus media, whereas the growth inhibition zone of cellulose and cellulose blank disks (negative control) were insignificant. Conclusion: Noticing the unique characteristics of bacterial cellulose as a dressing and its proven ability in absorption and release of ciprofloxacin hydrochloride, the prospects are seen for production of antibiotics containing dressings of this microbial product in future.

Background: Molybdenum is an essential trace element for both animals and plants. Molybdenum (Mo), which functions as a cofactor for a limited number of enzymes including xanthine dehyrogenase, aldehyde oxidase, and sulfite oxidase in mammals, is believed to be an essential trace element in animal nutrition. The aim of this study is to evaluate the hepatoprotective potential of sodium molybdate against carbon tetrachloride (CCl4) induced liver damage. Materials and Methods: In an experimental study, adult male rats received daily oral administrations of different doses of sodium molybdate (0.05, 0.1, and 0.2 g/kg bw) along with intrapertioneal CCl4 (50% CCl4 in olive oil, 1 ml/kg bw) twice a week for 28 consecutive days. Results: Histopathological examinations in CCl4-treated rats showed extensive liver injuries characterized by extensive hepatocellular degeneration and necrosis, fat degeneration, and inflammatory cell infiltration while histopathological changes induced by CCl4 were significantly attenuated by sodium molybdate treatment. Conclusion: The results of this study suggest that sodium molybdate could protect liver against the CCl4-induced oxidative damage in rats, and this hepatoprotective effect might be contributed to the protection of liver by preventing the toxic chemical reactions which generate oxidative stress, lipid peroxidation, and molecular changes which ultimately lead to liver tissue necrosis.
